Which legal principle requires that all evidence obtained by the government must comply with constitutional standards?

The Exclusionary Rule is the correct answer because it specifically mandates that evidence obtained in violation of a person's constitutional rights cannot be used in a court of law. This principle serves as a safeguard against unlawful searches and seizures, ensuring that the government adheres to constitutional standards when collecting evidence. If law enforcement obtains evidence through methods that breach constitutional rights, such as without a proper warrant or probable cause, that evidence is rendered inadmissible in court.

Other concepts, such as the Fourth Amendment, provide the constitutional basis for protecting individuals against unreasonable searches and seizures, but the Exclusionary Rule is the mechanism that enforces that protection in legal proceedings. The Good Faith Exception pertains to situations where evidence collected in good faith, despite a legal misstep, may still be permissible, and the Miranda Rule relates specifically to the rights of individuals during custodial interrogations rather than the broader principle of evidence admissibility.
